Effect of Mechanochemical Processing on the Oxidation of 3Nb + Al Mixtures

  • Published:
Inorganic Materials Aims and scope

Abstract

Mechanochemical processing is shown to influence the oxidation behavior of 3Nb + Al mixtures. As determined by thermogravimetric analysis and x-ray diffraction, mechanical activation leads to the formation of solid solutions. The processing time affects the reactivity of the mixtures. The highest reactivity is offered by the mixture ball-milled for 5 min: oxidation of this mixture during heating in air from 25 to 600°C results in the formation of Nb2O5 and Al3Nb.
